The purpose of this study was to predict and explain the senior high school students’ intention of fast-food eating behavior. The Theory of Planned Behavior (TPB) participants were 363 students who were studying in grade 1 to 3 in a senior high school in Nantou County in the school year of 2010. This research used two kinds of researching methods, one was open-ended elicitation, and the other was close-format questionnaire. The collected data was analyzed under the theories of Pearson product-moment correlation, one-way ANOVA, hierarchical multiple regression, multiple regression, and Hotelling’s T2.The four major findings were as the following: 1. A round 59.9% of respondents showed the positive behavioral to intention fast-food eating behavior in next month. 2. The attitude and subjective norm explained 13.9% of variance of the intention of the fast-food eating behavior; the perceived behavior control added 26.5% explanation power. Thus, the explanation power of these three variables accounted for 40.4%. 3. The attitude of respondents toward intention to fast-food eating behavior was moderately related to the product of behavioral beliefs multiplied by evaluations of outcome (Bi* Ei). The subjective norm of respondents’ intention to fast-food eating behavior was moderately positive related to the product of normative beliefs multiplied by motivations to comply (NBj* MCj). The perceived behavior control or respondents’ intention to fast-food eating behavior was also moderately related to the control beliefs multiplied by perceived power (ΣCi*Pi). 4. There were significant differences between respondents with the intention of fast-food eating behavior and respondents without the intention of fast-food eating behavior in behavior beliefs, outcome evaluation, normative beliefs, control beliefs, and perceived power. Generally, the results of this study support the hypothesis of TPB and reveal that TPB is better than the Theory of Reasoned Action on predicting the behavioral intention of nutrition health care. In the future, the influences of behavioral beliefs regarding the intention of nutrition obtained from the study can be included in the nutrition health care programs for the sake of upgrading the subjects’ intention of nutrition health care.高中生計畫行為理論攝取西式速食行為意圖senior high schoolTheory of Planned Behaviorthe fast-food eating behavioral intention
